Break work into milestones
Frontend, backend, API, QA — each should be a separate line item. Clients appreciate transparency and it makes scope changes easier to manage.
Invoice for hosting & domains separately
If you purchase hosting or domains on behalf of a client, list these as separate line items with a clear markup or at cost.
Use a monthly retainer invoice
For ongoing maintenance, send the same invoice monthly. Save it in our tracker and duplicate it each month.
Add your GitHub/repo reference
For technical clients, adding a PR or repo reference in Notes helps them match your invoice to the work completed.
